VAppiimttion mea August 30,1931).Y 'sgml No. 478;975;

' This invention relates to feed-water heaters for locomotives, andparticularly` to "one which is interposed in the path of the eX-haust-ing gases of a locomotive `iireebox so `as. e' to utilize thisheat, which would otherwlse with a .shouider 19., which fabuts fthe'interior be wasted. k

The object of the invention is to provide a heater, of the characterdescribed, which may be inserted laterally through the side of a lol-icomotive, and which is provided with means for allowing the watertherein to circulate with the water in the boiler of the locomotive towhich it is applied. Another object is tok provide a heater which willaccomplish the 'l just mentioned object, and which is of eX- trem'elysimple construction. Otherobjects may later become apparent. j

In the drawings, in which similar numerals refer to similar partsthroughout the sevv eral views, there is shown a locomotive 10v 15 ofthe locomotive, so that theV exhaust gases and smoke must pass under itbefore r they are discharged through the smoke stack 116 zofsthelocomotive.` TheloGGmQtivef'F-is shownf aequ-izpped' withl the"conventionalfspnmk arresting screen'l', and steam` exhaust; pipe y 18whichulcreates a draft i-nthegsmoke 'boXl- The-.opposite side `oftheft'anki =13fzis formed 65 wall ofthelocomotive shell, while iontheek-'z teriiorwalli va gasket 12.0 s pressed fby a retain-vingaendzpl-ate2l :both gasket and 4end vplatebee` Y, ing provided toVfbe 'inserted oven'rthe.-.s`h ml.i 60 l derediendfof thetank.

When.. the injector11 is not being operated, the tank 13 will 4`be in open` circulationwithrthe boiler, as the valve `28 will opento admit of thermosiphoniccirculation. A hand valve 29 may be 9" supplied to the pipe 12 so thatthe water feed-V ing therethrough may be positively outV oi.Thisinvention provides a feed-water heater of simplified design, whichmay be readily removed from a locomotive for repairs,mand fwn which,when not actually injecting water into the boiler of a locomotive, is inopen lcirculation therewith to prevent the formation of steam within thesystem. n

It is to be understood that this invention is not to be limited to theparticular form here shown Vand described, but that the appended .claims'are` to be broadly construed.

i I claim:

1.'A feed-water heater for locomotives Y Y provided with boilers'andwater injectors,

comprising an elongate tank: having aperfA tures formed at its top andlbottom portions and with a flangel at one end and a reduced oppositeend forming a shoulder, said tank being, adaptedy to beparrangedlaterally through the shell of vthefboiler Sorthat Vsaid `flange'x'abutstheexterior thereof, a collar Vfor insertionover the reduced end of said5 tank and .against the exterior offthe shell of the locomotive, whensaid lshoulder rests against the interior-of the shell,a pipe providedto connect a top "aperture of Said tank top-the boiler at apoint-beneath.the water l line thereof,xa pipe provided to connect the water injectorto a'bottom aperture of said tank, said last named pipe being providedwith a branch vpipe which is adapte'dto connect with the bottom fof theboiler, *andV check -valves interposednin said last named `pipe anditsfbranch pipe.V
